2 Claims.

This invention appertains to new and useful improvements in cropwindrowers or swathers and an important object is to provide anadjustable mount for the platform of the machine at a position betweenthe usual drive wheel and grain wheel, instead of in front of the grainwheel, thus eliminating the requirement for counterbalancing at the rearof the machine.

Another important object is to provide a crop windrower having a frameextension permitting the grain wheel to be mounted a sufiicient distancefrom the drive wheel so that the platform can be mounted between thesaid wheels with its longitudinal center in a vertical plane with theaxes of the wheels.

Still another object is to provide a crop windrower having a frameconstruction on which means is provided permitting vertical adjustmentof the platform, with the cutting bar and reel as one assembly, incounterbalanced position between the usual grain and drive wheels of thewindrower.

These and various other important objects and advantages of theinvention will become apparent to the reader of the followingspecification.

In the drawings:

Figure 1 represents a fragmentary top plan view of a windrower showingthe platform and lifting mechanism.

Figure 2 is a side elevational view showing the lifting means.

Figure 3 is an enlarged fragmentary perspective view showing the guideat one end of the platform.

Figure 4 is an enlarged sectional view taken substantially on the line4-4 of Figure 1.

Figure 5 is a horizontal sectional view taken substantially on the line55 of Figure 2.

Figure 6 is a perspective view of one of the internally threaded blocks.

Figure 7 is a sectional view taken substantially on the line 1-1 ofFigure 1.

Figure 8 is a fragmentary perspective View of the frame and one of theslide plates.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that numeral 5 represents the platform of the windrowerwhich includes its frame 6, at the forward portion of which is locatedthe cutting bar ll.

Rising from each end of the frame 6 is a slide plate 8 to the outer sideof which is secured a pair of vertically disposed cleats 9-9 providedwith guide flanges l 0, the same engaging behind guide flanges II on thevertical angle iron posts 12-12, which are secured at their upper endsas at l3 to the forwardly projecting frame members l4l4a. Through thesaid frame members l4-l4a the upper ends of the screw shafts l5 arejournaled and equipped with the bevel gears l6 N which mesh with bevelgears I! on the horizontal shaft [8. It can be seen in Figure 2 thatthese frame members I4-I4a are secured as at [4b to the elongatedtubular casing 5a.

. Each of the slide plates 8 is provided with an opening therein throughwhich the shank l9 on 103 the corresponding block 20 is disposed and acotter key or the like 20a is placed through the shank l9 to preventdisplacement of the block; from the corresponding plate 8. A

Each of the blocks 26 is provided with a vertically disposed threadedbore therein for receiving the screw shaft l5 while the lower end of thescrew shaft is disposed through an apertured guide plate 2|.

Numeral 22 represents the drive wheel on the shaft 23 which at one endis provided with the sprocket wheel 24.

A horizontally disposed shaft 25 is supported on the case So by bearings26 and this shaft 25 is provided with bevel gears 21 meshing with thebevel gears 28 on the adjacent end of the aforementioned shaft I 8.

Mounted adjacent the drive wheel 22 is the short shaft 29 having asprocket 30 thereon and. trained over the sprocket 24-30 is the sprocketchain 3|. On the shaft 29 is the gear 32 and pinion 33, the gear 32meshing with the gear 34 on the countershaft 35.

The shaft 25 is provided with a short shaft. extension 36 connectedthereto by the universal joint 37. This short shaft 36 has the gear 38carried thereby. The shaft section 36 extends through a horizontal slotin the supporting plate 39.

Numeral 40 represents the operating means for 40 the shaft section 36whereby the gear 38 thereon can be meshed with either the gear 34 on theshaft 29 or the gear 4| on the shaft 35. This determines whether thescrew shafts I5 are to be rotated one way or the other for lifting orlower- 45 ing the platform, cutting bar and reel assembly.

The means for adjusting the shaft extension 36 consists as shown inFigure '7 of an elongated connecting rod 42 having a collar 43 at oneend receiving the shaft section 36 and being pivotally connected at itsopposite end to the upstanding portion 44 of the lever 45. The mainportion of the lever 45 being bent substantially horizontal as shown inFigure '7, while the lower end of the 66 portion 44 is pivotallyconnected to the base plate 46. 7

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

What is claimed is: 1

1. A platform mount and lift for windrowers comprising a frame structureincluding a horizontal portion and pairs of vertically arranged postsdepending from the horizontal portion to slidably receive therebetween aplatform of a windrower having a frame, guide flanges on said posts, anaxle journaled on the frame structure ,with the pairs of postsstraddling the axle, a

ground power wheel secured on the axleadjacent one end thereof andarranged at one side of the frame of the platform, a ground wheelsupport- 7 7 ing the axle adjacent its other end and arranged onopposite side of the platform from said power wheel, upstanding platessecured on opposite sides of the platform frame andslidable between thepairs of posts, guide flanges on the plate and slidably engaging the'guide flanges of the posts for; slidably mounting the platform foradjust- 'ment towards and from the ground, vertically arzontal portionand pairs of vertically arranged posts depending from the horizontalportion to slidably receive therebetween a platform of a windrowerhaving a frame, guide flanges on said posts, an axle journaled on theframe structure with the pairs of posts straddling the axle, groundwheels supporting said axle and one of said wheels being secured on theaxle for rotating the latter by the forward movement of the framestructure, upstanding plates secured on opposite sides of the platformframe'and slidable between the pairs of posts, guide flanges on theplates and slidablyengaging the guide flanges of the posts for -slidablymounting the platform for adjustment towards and from the ground,vertically arranged screw shafts journaled on the frame structure andarranged between the pairs of posts, screwblocks meshing'with the screwshafts and pivotally connected on the upstanding plates, 'a sectionaldriven shaft having one section thereof journaled on the horizontalportion of the frame structure, means connecting said last-named sectionof the'driven shaft to the screw shafts, a mounting carried by thehorizontal portion of the frame structure and supporting the othersection of the driven shaft for rotation and a limited swinging vmovement, a gear securedto the lastnamed section of the driven shaft,intermeshing reversing gears journaled on the frame structure to havesaid first gear alternatingly mesh therewith and disconnected fromeither of the re-' versing gears by the swinging movement of thelast-named section of thedriven shaft, an op-'
